JAMES BALL, OF HOLYOKE, MASSACHUSETTS, ASSIGNOR TO THE HOLYOKE ENVELOPE COMPANY, OF SAME PLACE.

ENVELOPPE-MACHINE.

SPECIFICATION forming part of Letters atent No. 409,624, dated August 20, 1889.

llpplioaticu ledMarch 8, 1886. Serial No. 194,377. (No model.)

To @ZZ whom it may concern:

Be it known that I, JAMES BALL, a citizen of the United States, residing at Holyoke, in

the county of Hampden and State ot' Massachusetts, have invented new and useful Improvements in Envelope-Machines, of which the following is a specification.

This invention relates to envelope machines, the object being to provide an improved machine for gumming and folding the peculiar description of envelope known as registered package envelope, patented J une 4, 1878, No. i,422; and the improvements pertain to the peculiar organization ofdevices required for gummin g the end, back, and seal flaps of said envelope and folding the same, all as hereinafter fully described, and pointed out in the claims.

Figures 2 and 1 are perspective views of eooperating sections or divisions of an envelopemachine embodying my improvements, Fig. 1 being a front oblique and Fig. 2 a rear oblique View, the former showing a part of the envelope drying' chain connected therewith. Fig. 3 is a perspective view from the rear of a portion of Fig. 2, showing one end of the main picker, its eperatingbar, and the gumming devices, the opposite end being broken off, said iigure showing in dottedv lines the position of the main picker-gumming roller when moved away from the gum-box te gum said picker. Fig. 4L is a perspective view of the stop-motion mechanism embodied in Fig. 1, showing the table of the machine and certain parts of the frame of the latter, as hereinafter described, in dotted lines. Fig. (i is a per spective view of the front edge of the table of the machine, Fig. l, and of the vibrating flapbed pivoted thereon, together wit-h the immediatelyactuating mechanism thereof, shown in full and in dotted lines, said figure showing also the upper ends of the front vertical en velope-guides. Fig. 5 is a transverse section through the table and flap-bed, Fig. t, showing in end view the devices for vibrating said bed. Fig. 7 is a perspective view of a portion of the stop-motion mechanism illustrated in Fig. i, but showing certain parts thereof in the positions which they occupy when the 5o tlap-gunnning devices are stopped. Figs. S, il, and 10 illustrate in side elevations and in perspective the envelope grippers, Fig. 9 showing one shut, Fig. lO showing the upper end of one arm of the swinging frame to which the grippers are attached and a part of an arm on the table of the machine to which the gripper-opener is attached. Fig. 11 is a rear perspective view of that portion of' the table of the machine, Fig. 1, directly under which the envelope-lifter operates, showing above said table the mechanism by which the envelope is raised and held in position. when the grippers take it, and the means for closing the latter, the upper ends of both of said swinging gripper-arms with grippers thereon and an envelope just seized by the latter being shown in said figure. Fig. 12 is a side elevation of the division of the machine, Fig. 1. Fig. 13 is a plan view of the envelope above referred to. Fig. let is a side elevation of the united frame of said two divisions of the machine, much of the working mechanism being omitted. Fig. 15 is avertical cross-section of the table 3 shown in Fig. 2, and part of the mechanism mounted thereon, the view being taken just in rear of the bar 401, Fig. 2. Fig. 16 is a front elevation of the same, Fig. 2, looking in reverse direction. Fig. 17 is a vertical cross-section of that part of the machine shown in Fig. l, the section being taken justv in front of the cam-shaft 17, and part-s being omitted for clearness of illustration. Fig. 18 is a vertical longitudinal section nearly central of Fig. 1, paris being omitted for perspieuity. Fig. 19 is a similar section of Fig. 2, with omissions.

It will be understood that in many of the figures some parts are necessarily omitted or broken away and elsewhere shown in detail, the complex character of the machine mal;- ing clear illustration on a small scale very difficult.

In the drawings the two divisions of the machine are shown in Figs. 1 and 2 separated, in order that the parts thereof maybe illustrated upon a scale sufieiently enlarged to show clearlyT their construction and relative relations; but in practice said divisions constitute one machine having their frames united, as shown in Fig. 14C, the main shafts of the two said divisions being connected by a shaft and bevel-gears, as there shown.

IOO

In the drawings, 2 indicates the frame and 3 4 the tables of the machine, the former that of the first division, Fig. 2, and the latter that of the second division, Fig. 1, said divisions being so designated because they act on the envelope-blank in that order.

In Fig. 2, 5 is the driving and cam. shaft of the machine, rotary motion being given thereto by a suitable belt, and connection is made by like means between said driving-shaft and a roller-shaft G, on which is a roller co-operating with another roller, both located under the folding-box of the machine to take the folded envelopes from the latter and compress their folds. Said rollers are indicated in dotted lines, Fig. 19, and they are located sov as to drop the envelope onto the chute 7, Fig. 14, from whence it moves onto the trough 8 and is dropped onto the latter when the feed-arms 9 (Figs. 1, 12, and 14) are at the lower end of said trough, and they carry it up inconjunction with pivoted arms 10, Fig. 12, hung on a cross-bar between said feedarms, and push the envelope onto the slotted envelope-lifter 11, Fig. 4, opposite the corners of which are the vertical envelope-guides 12 13, the latter being' located at t-he rear of the table 11 and adapted to stop the envelope and hold it in proper position to be lifted up. The aforesaid arms 10, one of which is shown in dotted lines in Fig. 1 and one in full lines in Figs. 12 and 18, have their upper ends held up in the slots in trough 8, in which the arms 9 move (but in advance of the latter) by the spring 14, attached to the end of an arm on the said cross-bar between arms 9, a curved guidestrip 15 under trough 8 servingl to guide the ends of arms 10 downward when they move backward, whereby said ends pass under and back of an envelope which arms 9 have moved up and move said envelope upward in advance of the next one carried by arms 9. A pin or projection in at one side of one of the arms 10 engages the lower face .of the strip 15 to guide the arms 10 downward during the backward movement, the movement bein g a common one in feed-pawls. The arms 9 are hung on a rockshaft 16, to which motion is imparted by a suitable connection with the cam-shaft 17, Figs. 12 and 18, said shaft in Fig. 1 being shown with a driving-pulley thereon to indicate means for driving the same independently of the shaft 18 and the gearing shown in Fig. 14. The shaft 116, extending over trough 8, has thereon two pulleys, over which cords 117 run, and the latterserve to hold the seal-Hap of the envelope down as it passes up said chute.

In Fig. 2 the cam-shaft 5 is not shown extended across the machine under the table thereof. rlhis division of the machine is, with the exception of the below-described improvements which have been added to it to adapt it to the manufacture of said special envelope, substantially such as is shown in the patent to Reay, August 25, 1863, No. 39,702.

In Figs. 2 and 19, 2O is the gum-box, having a roller 25, as usual, rotating therein in the gum, which roller is attached to the shaft 21, and on the latter is a gear 22.

The picker-gunnning roll 23 is hun g in bearings on the horizontal bar 24, and on the shaft of roll 23 is a pinion engaging with said gear 22. The main picker 26 and the small picker 27 are both attached to the picker-bar 28, the latter having a reciprocating vertical motion by a suitable connection with the cam-shaft in the usual way. (See Fig. 19.) The bar 24, on which the gumming-roller 23 isl hung, has a reciprocating horizontal motion imparted to it by a vibrating arm 29, attached to each end of said bar, motion being imparted to the latter by suitable connection with the cam-shaft of the machine. By the said movement of bar 24 the rol is carried under and against the lower end of the picker 2G, gumming the latter and its horizontally-proj ectin g arm 290. (Shown partly broken off in Fig.3 and in dotted lines in Fig. 2.) rIhe small picker 27 is gummed by any mechanism common in this class of machines. The said picker 2G strikes and gums the inner side of the back iiap 30 of the envelope 31, Fig. 13, below the laps 32 33 34 and the center lap At the same time and by the same movement of the cross-head 28 the small picker 27 is carried against and gums the inner side of the end flap 35 of the blank, and said two pickers, when they rise up, lift up said blank so that the carriage 3G passes under it, and, engaging with it in the usual way, draws it backward over the usual folding-box 37, one of the wings of which 38 is shown in Fig. 2. The shaft 48, having thereon two pinions, as shown, is rotated by a belt-connection with shaft 6, and as the blank is carried under said pinions the latter rotate in close proximity to laps 32 34 of the envelope and prevent them from turning up and striking the plunger 41 as the blank passes under it. The blank for the aforesaid envelope is of such extraordinary large size, and the paper from which it is necessarily made is so much heavier than that ordinarily used, that it is found indispensable to provide in a machine for gumming and folding said blank some means for supporting the central part of the blank while its ends rest upon the carriage 3G and during its movement from` under the pickers to the folding-box, and it is also requisite, in order to obviate too slow motions of the machine, that said means for holding up the central part of the blank shall not in any way interfere with the regular reciprocating motions of the folding-plunger, and to this end the carriage 3G has attached to its rear crossbar the rigid arm 39, having the plate 40 on the free end thereof, or having the end of said arm made wide. The said carriage has the usual reciprocating motion over the folding-box 37 by means of the vibrating arln 400, which has the usual connection with a rock-shaft on the lower part of the ina- IOO IIO

chine. lVhen the carriage moves forward to engage with a blank, as aforesaid, the plate 40 is carried under the center of the latter, and the blank is held in a level position by the carriage and said plate while it is being carried over the folding-box; but while the blank is being drawn back the folding-plunger 41 must move up in order to be ready to move downward against the blank as soon., as the latter arrives over the folding-box, and also must the carriage and plate 40 move forward while said plunger is in the foldingbox. rlherefore said plunger is made in two parts, as shown, each of which is secured to the opposite ends of a yoke 42, thereby forming a slot 43 through said plunger, and a passage for plate 40 above the latter, which permit the plunger to move vertically while arm 39 is over the folding-box, and plate 40 to be carried forward through yoke 42 above the plunger while the latter is in the folding-box. Said plunger-yoke is attached to a verticallyreciprocating cross-head 401, (shown in `dotted lines in Fig. 2,) in the usual manner. The said blank 31 has the under sides of the laps 32 and 34 gummed before it is placed on the machine, and a pile of blanks so prepared is placed on table il, Fig. 3, under the pickers 2G and 27, from whence they are taken one by one by the latter, whereby the gum is applied to the inside of the back-flap and' to the same side of the central lap 33, (the latter by the arm 290 on picker 26,) and they are folded and delivered through the bottom of the folding-box 37 onto the chute 7, Fig. 14, which is located under said folding-box, in the condition shown by the envelope 3l, Fig.- 13, excepting that the seal-iiap 44,which is there shown open, is folded against the outer sides of the laps 32, and 34, and in this condition the envelopes are fed one by one up the trough S, Figs. l and 14, on to the envelopelifter 11. (Shown in Fig. 4, and hidden in Fig. 1 by an envelope shown thereon under the gumming devices.)

That part of the machine which receives the envelope, as just described, applies the gum lirst to the outside of the seal-flap thereof 44, at points thereon directly opposite the ends of the laps 34, and in such manner as to conform to the shape of said laps, to the end that the gununed surface on the outside of said seal-flap shall not extend beyond the borders of said laps when the edge of the flap is placed under the latter and theyare gunnned thereupon 3 and, secondly, following the abovementioned gumming operation, the seal-flap 44 is folded outward to bring its inner side upward, and then gum is applied thereto nearly over its whole surface; and, finally, the envelope is seized by grippers and carried from the envelope-lifter 1l into the dryingchain 45, from which it 'is dropped into the chute 4G, where the finished envelopes are gathered and bound into packages containing a convenient number. The said envelopelifter has a slot 47 in its rear edge, for a purpose hereinafter*described, and is supported under the envelope 31 (shown in Fig. l) on a post which rests on a cam on shaft 17,where by said lifter is given a vertical reciprocating motion. At the deposit of each envelope on said lifter by the arms 9 and their co-operating parts, as hereinbefore described, said lifter rises from the position shown in Fig. 4 to about that indicated in Fig. 1, the rise bcing equal to the height of the envelope 31 there shown, and immediately following said movement of the lifter the two ends of the arms 49, Fig. 1 1, attached to the rock-shaft 50, swing upward through the slots 51 in the rear edge of said lifter against the envelope, raising` the rear edge of the latter off from the lifter and carrying it up against the stop-arms 52, same figure, the lifter meanwhile dropping to receive another envelope. Said shaft 50 is given its rocking motion by the connecting-rod 53, which is pivotally attached to arm 54 on said shaft, and whose lower end rides on a suitable cam on shaft 17. The arms remain in said position but an instant, or just long enough to hold the envelope in place while its seal-flap is being gummed, as below described, and immediately said arms, together with the arms 52, rise slightly higher to bring the envelope in the track of the grippers below described. (See Fie'. 1S.) Said arms 52 are rigidly attached to the sleeves 55, having thereon rearward projections, as shown, and said sleeves are fixed on the crank-shaped shaft 5G, the ends of the latter being hung in suitable bearings on table 4, Fig. 1, and a suitable vibratory motion imparted thereto by the connecting-rod 57, which is attached to the arm 5S on said shaft. (See Fig. 12.) Said connecting-rod has one end riding` on a suitable cam on shaft 17, whereby it is given an upward movement, and a spring 59 attached to said arm draws the lat-ter downward and holds the end of said rod against said cam.

Vhile the envelope is held by the arms 4f) and 52, as above described, its seal-flap is gummed as follows: It will be remembered that said sealdlap at this stage of the operation lies on the ends of the laps 34. A Hap-table is hung on table 4, as shown in Fig. l, and its front edge is lifted by the swinging lever G1, which is pivoted on table 4 under table GO, the free end of said lever acting against the inclined under side of said table, as shown in Figs. 5 and G. A vibratory motion is given. to lever G1 by the elbow-lever (52, to one arm of which the lever (31 is connected, and lever (52 is given a rocking motion by the connecting-rod (53, whose lower end rests on a suitable cam on shaft. 17. rlhe front edge of table GO is provided with two circular recesses 64, (sec Figs. 1 and (5,) having somewhat the forni of the envelopelaps 34, and said front edge swings by gravity against table 4 of the machine. A crankshaft is hung in suitable bearings on table 4, Fig. 1, and extends over the Hap-table G0,

IOO

IIO

and has thereon the circular short arms GG, which, by the motion of shaft G5, are rocked downward into said recesses G4 in table 60, and then upward to the position shown in Fig. 1. Said crank-shaft G5 has on one enda pinion, as shown in Fig. 1, with which a vertically-reciprocating rack (also there shown) engages, whereby shaft 05 is given said rocking motion, said rack being actuated by suitable connection with a cam on shaft 17. The said arms 06 on shaft 05 are picker-gummers, and apply the gum to the outer surface of the seal-flap of the envelope at two separate points, as follows: The gumming-roll 07 takes gum from a roll on shaft 0S, which roll rotates in the gum-box 09, in the usual manner. The gnmming-roll 67 is hung on the lower ends of two arms 70, which are attached to a shaft 71, and the latter is given'a rocking motion by its connection with the vibratory elbow-lever 7 2, Fi 12, through the rod 7 3, said elbow-lever being connected to the rod 74C, which is given a reciprocating endwise motion by a suitable cam on shaft 17. Vhen said pickcr-gummers 00 lie within the recesses 64E in the vibrating table 60, the face of the latter drops down below the plane of the face of said gummers, (an envelope at this instant rising up back of table 00,) and while there the gumming-roll 67 swings over said gummers, applying gum thereto. Immediately after, shaft G5 swings up and over, carrying` the gummed face of the gummers 66 against the outside of the seal-flap of the envelope, applying gum thereto and becoming adhesively attached to said iap thereby, and instantly said gummers swing back to their place of starting, opening out said seal-flap and laying it over the face of the table 60, which then rises up to a level with said gummers, and at this instant the gumming-roll 75, which has a vertical and a horizontal reciprocating motion, is carried over the inside of the seal-flap of the envelope, gumming the latter. Said gumming-roll 75 takes gum from the gum-box 76 and is hung in the ends of the rods 77, which are pivotally attached to the arms 7 8 on the rock-shaft 79, whereby the gumming-roll 75 is given its vertical motion, shaft 79 being given its rocking motion by the rod S0, connected to arm S1 on said shaft, rod 80 being given a verticalreciprocating motion by its connection with a suitable cam on shaft 17. The horizontal reciprocating motion of the gumming-roller 75 is imparted to it by the connection of the lower ends of the said rods 77 with the arms S2 on a rock-shaft 83 by the rods S4. Immediately that the inside of said seal-flap has. been gummed, as just described, the grippers swing forward opposite each end of the envelope, as shown in Fig. 11, and catching the latter quickly draw it backward (the arms. 49 and 52 at this instant moving away from the envelope and releasing it) and .deposit it in the drying-chain 45, the latter having an intermittent motion around suitable shafts in the usual manner. Fig. 11 illustrates the envelope in positionV between the said arms 49 and 52, showing its seal-ap 44 opened out as it is when it is gummed, and also shows the position of the grippers at the moment they seize the envelope. The gripper S5 consists of the bar101, having the rigid jaw-piece thereon,-and having the jaw 102 pivoted to its upper end and adapted to open and close opposite said fixed jai r-piece. Said jaw 102 has the projection 103 on its rear end, and a latch 10a is pivoted on bar 101, having a pointed projection 105 thereon. A spring 106 is attached to the side of said latch, whose upper end is hook-shaped and eX- tends .under a pin in jaw 102, which serves to open jaw 102 and to swing said latch.

-Said grippers are secured on the uppe'r side of two vibrating arms 8G, (see Figs. 11 and 12,) which are secured on a rock-shaft S7, and the latter is given a rocking motion by a suitable cam on shaft 17, with which an arm (dotted lines, Fig. 12) on said shaft engages. At a proper time the arms 8G swing the grippers (then being open, as shown in Fig. 10) toward the envelope, carrying the fixed-jaw part of the gripper under the end of the envelope, as shown, and bringing the pivoted jaw 102 into engagement with the under side of the sleeve 55 on shaft 5G, whereby said jaw is made to close against the upper side of the envelope, and said movement of the jaw carries the projection 103 thereon above the point 105 on the latch, letting the latter catch under said projection and lock said jaw, thereby causing the latter to grip and hold the envelope when the jaws move from under said sleeves 55. At the extreme backward movement of said grippers they encounter the pointed grippertrip S9, Figs. 1 and 10, which is fixed on the side of a standard 8S on table 4, and whose end enters between the latch and bar 101, drawing the latch away from the projection 103 on the rear end of the jaw 102, letting the latter open by the action of spring 106 and leaving the envelope free in said drying-chain.

To prevent the action of the gummingroller 75 when no envelope is present in the machine by reason of the accidental stoppage of the supply to the lifter ll-whereby if it were allowed to act uninterruptedly gum would be deposited directly on the table G0, Fig. G, greatly to the hinderance of the work and the waste of envelopes-the below-described stop-motion devices are provided. As before described, the crank-shaft 65 has a IOO IIO

rocking motion, and on one end thereof is the said vibrating table G0. The purpose of said stop-motion devices is to cause the rocking` motion of said shaft 79 to cease and the roll 7 5 to remain suspended where no envelope is present, thereby obviating said inconveniences. Said hook-bar moves up and down with the rocking motion of shaft 79 and passes through a slot in a guide 93, and said cam-curve 107 thereon strikes the guide at the end of said slot as it moves, a spring 9G attached to its free end serving to draw the bar toward said end of the slot in guide 93, so that when arm 95 makes a downward movement coincident with the downward movement of the said roll the said cam curve, by striking said guide, causes the lower end of bar 92 to. swing away from the pin 91 in disk 90 and prevent hook 94 from engaging with said pin; but when shaft 79 is to be stopped, as aforesaid, hook 94 engages with said pin before the said cam-prow jection strikes the guide 93 and arrests roll 75 in an upward position. To ei'tectthe stoppage of bar 92 by pin 91, as aforesaid, the hook 97, Figs. 4 and 7, is pivoted by one end to the table 4, and its upper end is connected by a rod 108 to the end of an arm 109 on the shaft 110, the latter having fixed thereon the finger 111. The shaft 110 is hung in a support 112, and has two arms 113 thereon, and the upper ends of two spring-levers 114 are interlocked with said arms and support, as shown. Said spring-l evers consist of flexible metallic strips, whose lower ends are engaged with a suitable cam on shaft 17, whereby shaft 110 is given a constant rocking motion, but of weak power, to the end that finger 111, to which shaft 110 imparts a vibrating motion, may be stopped in its movement toward the lifter 1l by an envelope which lies thereon, the said iiexible strip which so actuates said finger being capable of sufficient iiexure under such light resistance as to produce said effect; but when no envelope is present on the lifter finger 111 freely vibrates in slot 47 in the lifter, thereby permitting shaft 110 to rock correspondingly and the end of arm 99 to so swing as to throw the upper end of hook 97 forward, bringing it in the path of the oscillating movement of the pin 91, and the latter then engages with said hook, whereby it is rigidly held, and the next downward movement of the hook-bar 92 brings its hook 94 aga-inst the upper side of said pin, as in Fig. 7, thereby stopping the motion of shaft 79, which would otherwise let the gumming-roll 7 5 move down as usual against the table G0 and apply gum to that instead of to the seal-flap of the envelope.

That I claim as my invention is l. In a machine for gumming and folding envelopes, the blank-carriage 30, having a reciprocating horizontal motion, a blank-supu porting arm attached to one end of said carriage and extending between the sides thereof combined with the yoke 42, having a divided folding-box plunger attached thereto,
